High‐power laser sources are widely used in industrial precision processing and act as a
new platform for strong‐field physics research using peak power over petawatt. This review …

The rise in output power from rare-earth-doped fiber sources over the past decade, via the
use of cladding-pumped fiber architectures, has been dramatic, leading to a range of fiber …

The brightness of doped luminescent materials is usually limited by the ubiquitous
concentration quenching phenomenon resulting in an intractable tradeoff between internal …

Imaging speed is one of the most important parameters that define the performance of
optical coherence tomography (OCT) systems. During the last two decades, OCT speed has …

We analyze the scalability of diffraction-limited fiber lasers considering thermal, non-linear,
damage and pump coupling limits as well as fiber mode field diameter (MFD) restrictions …

We report an 8-element spectral beam combination of Yb-doped all fiber superfluorescent
sources around 1070 nm wavelength. Each source consists of a 60 mW front-end and a 1.5 …

Ultrafast fiber lasers have gained rapid advances in last decades for their intrinsic merits
such as potential of all-fiber format, excellent beam quality, superior power scalability, and …

We review recent achievements with ultrafast bulk lasers and amplifiers based on Yb: YAG
and Yb: glass. Special attention is paid to those aspects of the quasi-three-level nature of …

The threshold-like onset of mode instabilities is currently the main limitation for the scaling of
the average output power of fiber laser systems with diffraction limited beam quality. In this …

Strongly pumped fiber lasers are analyzed, based on a rate equation model. Examples
include Nd/sup 3+/-doped and Yb/sup 3+/-doped fiber lasers, with distributed Bragg reflector …
